BACKGROUND AND PURPOSE Our research focuses on interventional neuroradiology (stroke treatment including imaging methods) and general neuroimaging with an emphasis on functional MR imaging. Our aim was to determine the efficacy of revascularization (TIMI) of middle cerebral and/or carotid artery occlusion by means of mechanical recanalization techniques and(More)
BACKGROUND AND PURPOSE Although early identification of patients at risk for dysphagia is crucial in acute stroke care, predicting whether a particular patient is likely to have swallowing problems based on the brain scan is difficult because a comprehensive model of swallowing control is missing. In this study whether stroke location is associated with(More)
Progressive multifocal leucoencephalopathy (PML) is an opportunistic infection caused by human polyomaviruses such as the JC virus. It usually occurs as a severe complication of immunosuppression in patients with primary disorders of the immune system or secondary impairment of immune function, for example , after iatrogenic states of immunosup-pression.(More)
Virchow-Robin spaces ensheathe the penetrating vessels of the brain. They communicate with the subpial space, are filled with interstitial fluid and contain a specific population of macrophages.Virchow-Robin spaces are a common finding in both CT and MR imaging. Recent radiologic studies have led to a concise definition of Virchow-Robin spaces.Virchow-Robin(More)
BACKGROUND The first ever diagnosis of multiple sclerosis (MS) requires consideration of both diagnostic criteria and differential diagnosis. Clinicians are particularly challenged by rare conditions which may mimic MS symptoms and relapses. CASE REPORT We report the case of a young female patient who presented with relapsing left hemispheric symptoms(More)
PURPOSE The increased T1 relaxation times at 3.0 Tesla lead to a reduced T1 contrast, requiring adaptation of imaging protocols for high magnetic fields. This prospective study assesses the performance of three techniques for T1-weighted imaging (T1w) at 3.0 T with regard to gray-white differentiation and contrast-to-noise-ratio (CNR).
